Very Very Simple ......   I have call display and an answering machine .... I never NEVER answer calls that I do notrecognise....  if it is important they will leave a message ..... they never do..... I no longer stress out over those  But*holes

They called and didn't leave a message. I called back - machine answers. Says "thank you for calling WCA customer service, we recognize your number as a customer. We tried to call you earlier but couldn't reach you".  then it goes on to say that someone entered my number in an online contest for a trip or something. this claim is untrue and I believe it is simply a scam to try to cover their a***s because they are breaking the Do Not Call rules. I will be reporting them to CRTC. Funny, though. I seem to be getting more telemarketing calls since I updated my number on the Do Not Call list a month ago.Thanks CRTC!

just blocking this number in my voip.ms ...it was a recording telling me that I'd been entered into a draw.. bla bla bla....

I got 5 MISSED call within a minute.  I was wondering that who called me.  I called back machine answers. so annoying.

I just dont answer those calls, use these sites to enter phone numbers..shows how large the problem is

They call us (do not call list) in Ontario. They do not leave any message.
